Before the cloud subscription model, Yvert released physical hardcover books that included a companion CD-ROM.
While there is no official, free "Yvert et Tellier catalogue PDF" for current editions, the publisher offers a modern Online Library (Bibliothèque en Ligne)
: Their success was built on a robust, permanent numbering system that remains consistent across editions, making it easy to track specific issues over decades.
: Essential for collectors of Mayotte , New Caledonia , French Polynesia , and TAAF .
Remember: support the hobby. Avoid illegal downloads that hurt the publisher. Instead, purchase an official PDF, or save up for a subscription. The cost is modest compared to the value it brings to your collection – and in the world of rare stamps, knowledge is the most valuable watermark of all.
Occasionally, collectors sell their previous year’s digital license. While the publisher discourages this, it is not illegal in the EU if the original owner deletes their copy. Look for "Yvert et Tellier 2022 PDF license" – these are much cheaper than the current edition.
